Attack Speed Discrepancies Between In-game and PoB

As I was min-maxing the attack speed on my cospri build I noticed discrepancy between the PoB attack rate and the in-game tooltip.

using https://pastebin.com/x9iiZG8W as build reference:

PoB says 6.44 attack rate, however in-game it says 6.45, slightly higher than PoB
If you add the 5% attack speed jewel Cataclysm Shrine into the empty socket PoB says 6.72 while in-game says 6.71, slightly lower this time
Finally if you turn on elusive for the 15% attack speed, PoB says 7.53, which is perfectly just under cospri's 7.57 breakpoints, however in-game it says 7.58, this time higher than PoB and also above the breakpoint.

Obviously it is 7.58 unless something is going horribly wrong with the in-game tooltip but bouncing back and forth between which one is higher is a bit puzzling.

Commencez par reproduire les trois comparaisons de vitesse d’attaque du build Pastebin lié : la configuration Cospri de base, le Cataclysm Shrine jewel et les 15% attack speed d’Elusive. Suivez le calcul de la vitesse d’attaque utilisé par PoB et comparez son arrondi ou sa gestion des breakpoints avec le tooltip en jeu ; le travail est terminé lorsque l’écart est expliqué et que le taux affiché est corrigé ou confirmé.
